Often after rebooting a server, it starts responding to pings even though you can’t remote on to it quite yet.
If you want to stop wasting your time continually trying to RDP into a newly-rebooted server, you can download a handy tool called tcping.
After you download tcping, you can drop it into your c:windowssystem32 and use it in a similar way to ping. For example, I did this:
tcping –t okc-fs-01 3389
That continuously checks Port 3389 to see if it’s open. Once it’s open, you see that and you know you’re ready to remote on to the server.
That’s all there is to it!
